$PECIFIGATION forming part of Letters Patent No. 697,940, dated April 15, 1902.

Application filed April 5,1901. Serial No. 54,532. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL ALFRED HAINES, a citizen of the United States, residing at Garrett, in the county of Ellis and State of Texas, have invented a new and useful Vrench, of which the following is a specification.

This invention relates to certain improve ments in axle-nut wrenches in which the wrench may be engaged with the wheel in such manner that the nut may be unscrewed by rotating the wheel.

The principal object of the invention is to provide a device of simple and economical construction which may be readily applied to the nut and wheel-hub, as more fully set forth hereinafter.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure l is a perspective view showing the complete wrench. Fig. 2 is a sectional view taken longitudinally of the wheelgripping jaws and showing the wrench applied, the extremities of the handles of the jaws being shown in elevation.

Referring now to the drawings, the present wrench consists of a cross-sectionally-angular socket portion 5 of box shape and having such dimensions as to snugly receive the end of an axle-nut to be removed or applied, and two of the diametrically opposite sides 6 of this socket portion are continued rearwardly to form ears 7, through which are passed the two pivot bolts or rods 8 and 9 adjacent to the side edges of the ears, but spaced inwardly from the ends of the ears.

Two jaws are provided, each consisting of a gripping portion 10, having a transverselycurved outer face and a flat inner face, said jaw also includinga handle portion 11, curved in such manner that when the flat faces of the gripping portions are disposed toward each other these handles will diverge rearwardly with compound curves. The handles are transversely corrugated, as shown at 12. The jaws are disposed with their gripping portions 10 between the ears 7 and have ears 13, which are perforated to receive the pivot bolts or rods 8 and 9, the positions of the jaws being such that when they are moved toward each other their flat inner faces will fit against the outer opposite faces of the nut-receiving socket portion, as illustrated in Fig. 1 of the drawings. Thus the portion 5 with the gripping ends of the jaws may be entered in the end of a very small wheel-hub, to receive a nut in the socket, and the handles may be then operated to expand the jaws and impinge the outer curved faces thereof against the inner surface of the wheel-hub, and to hold the jaws in this position a ring 15 is provided and is slipped over the handles and is adapted to engage in the corrugations of the latter, so that the ring will be held securely from slipping. By then rotating the wheel the socket portion will be rotated and therewith the axle-nut to disengage the latter.

In order that the wrench may be used for other purposes and also to provide a handle for the socket portion 5 that will permit of rotation thereof independently of the wheel to start the nut when it holds exceptionally fast, a handle or lever 16 is provided and extends laterally from one of the ears 7 of the socket-piece and at right angles thereto, and the extremity of this handle portion or lever is notched, as shown at 17, to receive nuts of different sizes.

What is claimed is An axle-nut wrench comprising an angular socket portion adapted to extend partially within the wheel-hub to engage the nut, an integral handle extending from the socket portion at an angle to the axis thereof, said socket portion having two rearwardly-extended oppositelydisposed walls forming spaced pivot-ears, jaws pivoted between the cars at points within the external lines of said socket portion, the inner fiat faces of said jaws being adapted to fit snugly against the exterior walls of the socket member to permit of the entrance of the wrench within a small wheel-hub and the outer faces of said jaws being rounded for engagement with the. In testimony that I claim the foregoing as inner Wall of the hub, transversely-corrumy own I have hereto affixed my signature in gated operating-handles for said jaws, and a the presence of two witnesses.
